Species Stresses and Threats and Forest Plan Strategies F - iv FINAL ENVIRONMENTAL IMPACT STATEMENT GEORGE WASHINGTON NATIONAL FOREST APPENDIX F – SPECIES DIVERSITY REPORT 1.0 INTRODUCTION Planning for ecological sustainability is an iterative two-stage process that involves first providing for a diversity of ecosystems and then by developing additional direction to meet the biological needs of specific species or species groups. Most plant and animal species will be sustained by managing for a diversity of ecosystems in the Plan area. However, additional provisions may be needed to help provide ecological conditions for specific species such as federally listed threatened and endangered (T&E) species, sensitive species and locally rare species. This Species Diversity Report is a supplement to the Ecosystem Diversity Report, which described how
